6 Definitions
The terms defined in the Schedule 1 - Dictionary have the meaning given when used in this instrument.
7 Kind of injury, disease or death to which this Statement of Principles relates
(1) This Statement of Principles is about otitis externa and death from otitis externa.
Meaning of otitis externa
(2) For the purposes of this Statement of Principles, otitis externa:
(a) means an infectious or non-infectious inflammation of the external auditory canal; and
(b) includes:
(i) acute diffuse otitis externa;
(ii) acute localised otitis externa (furunculosis);
(iii) eczematous otitis externa;
(iv) malignant otitis externa;
(v) acquired cholesteatoma of the external auditory canal; and
(vi) otomycosis.
Note 1: Otitis externa may be acute or chronic.
Note 2: Typical symptoms of otitis externa include ear pain, pruritus, discharge and hearing loss.
Note 3: Otitis externa may be accompanied by inflammation of the auricle.
Note 4: otomycosis is defined in the Schedule 1 - Dictionary.
(3) While otitis externa attracts ICD‑10‑AM code H60, H62.0, H62.1, H62.2, H62.3 or H62.4, in applying this Statement of Principles the meaning of otitis externa is that given in subsection (2).
(4) For subsection (3), a reference to an ICD-10-AM code is a reference to the code assigned to a particular kind of injury or disease in The International Statistical Classification of Diseases and Related Health Problems, Tenth Revision, Australian Modification (ICD-10-AM), Tenth Edition, effective date of 1 July 2017, copyrighted by the Independent Hospital Pricing Authority, ISBN 978-1-76007-296-4.
Death from otitis externa
(5) For the purposes of this Statement of Principles, otitis externa, in relation to a person, includes death from a terminal event or condition that was contributed to by the person's otitis externa.
Note: terminal event is defined in the Schedule 1 - Dictionary.
8 Basis for determining the factors
The Repatriation Medical Authority is of the view that there is sound medical‑scientific evidence that indicates that otitis externa and death from otitis externa can be related to relevant service rendered by veterans, members of Peacekeeping Forces, or members of the Forces under the VEA, or members under the MRCA.
Note: MRCA, relevant service and VEA are defined in the Schedule 1 - Dictionary.
9 Factors that must exist
At least one of the following factors must as a minimum exist before it can be said that a reasonable hypothesis has been raised connecting otitis externa or death from otitis externa with the circumstances of a person's relevant service:
(1) participating in aquatic activities within the ten days before the clinical onset of otitis externa;
Note: aquatic activities is defined in the Schedule 1 - Dictionary.
(2) being exposed to hot and humid weather conditions or heavy rains, on at least ten days within the 30 days before the clinical onset of otitis externa;
Note: hot and humid weather conditions is defined in the Schedule 1 - Dictionary.
(3) undergoing a course of therapeutic radiation for cancer, where the affected ear was in the field of radiation, before the clinical onset of otitis externa;
(4) having trauma to the external auditory canal of the affected ear within the ten days before the clinical onset of otitis externa;
Note: Examples of trauma include a blunt or penetrating injury, a surgical procedure and blast force.
(5) having a foreign object or implement inserted into, or removed from, the external ear canal of the affected ear within the ten days before the clinical onset of otitis externa;
